USA is definitely the most car-brained nation, but I don't think that miles-travelled alone stacks up when comparing states.
As an example for 2022 data from FHWA it shows that Mississippians drove 17,699 miles average, while Minnesotans drove more, at 17,887 miles. Yet Mississippi has more than triple the road fatalities.
Even if you take Mississippi as an outlier, many other states are well over double Minnesota, with similar miles-driven: South Carolina, New Mexico, Oklahoma.
